A rare case of antepartum posterior reversible encephalopathy syndrome

Abstract

Pre-eclampsia and eclampsia are well-known causative factors of posterior reversible encephalopathy syndrome (PRES). There are only a few reported cases of antepartum PRES. We report a 25-year-old primigravid woman who presented with eight months of amenorrhoea and an abrupt onset of eclampsia associated with a history of a fall. A computed tomography scan ruled out intracranial haemorrhage and PRES was diagnosed. She responded well to supportive care, labour was induced and maternal and neonatal outcomes were good. Antepartum PRES poses different challenges to those of PRES in non-obstetric or postpartum patients, because of the additional management aspects required to ensure foetal wellbeing. We were posed with a difficult decision about the disadvantages of caesarean section versus those of vaginal delivery in our patient.
